GeoTIFF Contour Generator

Generate bounded GeoJSON contour segments from a GeoTIFF band at a chosen interval and download them without server processing.

Contours are cell-based segments capped at 100,000 features; increase the interval for noisy or high-resolution rasters.

Choose a GeoTIFF up to 32 MB and 25 million pixels.

Understanding GeoTIFF Contour Generator

Cells, bands and derived values

Generate bounded GeoJSON contour segments from a GeoTIFF band at a chosen interval and download them without server processing.

GeoTIFF Contour Generator calculates from raster cells arranged in rows, columns and bands. Resolution, nodata values, band meaning and the raster CRS affect every derived value.

How to validate the analysis

Contours are cell-based segments capped at 100,000 features; increase the interval for noisy or high-resolution rasters.

Before interpreting GeoTIFF Contour Generator, check band selection, units, nodata handling and edge cells. Browser-generated results should be compared with known values for important work.
